When the overlays are hidden or the previews overlays are hidden, it is more consistent to have the preview toggle button hidden than shown.

This patch also removes the preview rendering when the previews are hidden.

Actually, I think this should be && instead of ||?

But look at node_draw_basis, it doesn't check SN_OVERLAY_SHOW_OVERLAYS for show_preview which I guess is a mistake?

(!(snode.overlay.flag & SN_OVERLAY_SHOW_OVERLAYS) || !(snode.overlay.flag & SN_OVERLAY_SHOW_PREVIEWS))
<=>
!(snode.overlay.flag & SN_OVERLAY_SHOW_OVERLAYS && snode.overlay.flag & SN_OVERLAY_SHOW_PREVIEWS)

It is a mistake, but not a problem, because the extra info panel is hidden with the SN_OVERLAY_SHOW_OVERLAYS flag. I'll correct that to be more consistent and maybe avoid getting previews for nothing.

I wonder if the preview acquisition could be moved inside the node_draw_extra_info_panel function. It would make it more consistent and avoid some double checks of the flags and redundancy.

After thinking longer, it is not possible to do, because we need to know the size of the node including its preview before drawing.
